Refactoring: Wrap in Container, Change Layout Type, Extract

This changeset adds refactoring support for 3 visual refactoring
operations:

(1) Wrap in Container. This can be invoked on one or more sibling
    views (or the root view) to add a new layout container into the
    hierarchy which "wraps" the views. The refactoring can also update
    the layout attributes (such as RelativeLayout attachments) such
    that they refer to the new container instead. If invoked on the
    root element, the namespace declarations are migrated from the old
    root to the new root.

(2) Change Layout. This can be invoked on a layout view to change the
    type of layout. In addition to editing the XML type declaration,
    it also removes layout parameters that no longer apply, and
    depending on which layout you are converting from and converting
    to, it may attempt to perform some translation to preserve the
    layout characteristics.  In particular, if you convert from a
    LinearLayout to a RelativeLayout, then it will use RelativeLayout
    params to emulate the old LinearLayout by attaching items below
    (for vertical layouts) or to the right of (for horizontal layout)
    the previous sibling, and if the baseline property was set on the
    LinearLayout it will also add baseline constraints on the
    RelativeLayout. (It also adds default ids on any elements that
    need it.)

    There is a LOT more we can do to support layout transformations;
    this is just a beginning.

(3) Extract as Include. We already had this feature, but it performed
    its own XML document manipulation.  This code has been rewritten
    to use the Eclipse refactoring support (which the other two
    refactorings are implemented to use as well), which among other
    things means that you get Preview support - you can press Preview
    from the refactoring dialog to see the edits before they are
    made. This rewrite is also necessary to support an upcoming
    feature: the ability to replace occurrences in other
    configuration-variations of this layout; for that we need to
    ability to do multi-file changes which the refactoring support is
    ideal for.
